Print to PDF modifying my form

I've built a New Nintex form - I have everything just about set up to where it's functional for my office. The only issue is the print to PDF function - when I hit Print to PDF link and the PDF opens, a lot of my labels are missing, the font color has been changed from white to black, and the multi-lined text blocks won't expand to ensure all of the data is in the PDF. Has anyone else had this issue and been able to resolve it - please help
